National Quantity Strategy: 10 projects and two EquipEx + selected as part of Priority Research Program and Equipment (PEPR)

Priority Research Programs and Facilities (PEPR) aim to build and consolidate French leadership in scientific areas that are considered priorities at national or European level and are linked – or are likely to be linked – to a large-scale transformation, whether technological, economic, societal, health or environmental.

Quantum Technologies PEPR, which supports the highest level of research activity in the world, is intended to strengthen national efforts in this area and to feed the actions further downstream of the national quantum strategy, such as the National Hybrid Quantum Computing Platform HQI (HPC-Quantum Initiative) launched on January 4, as well as the emergence of industrial activities.

After a phase of discussion with the state, which was based on a broad consultation of the community, ten major projects were identified, covering four themes:
Development of robust solid-state qubits for quantum computing;
– The development of qubits and sensors based on cold atoms;
– Development of error-correcting codes, quantum algorithms and post-quantum cryptography solutions;
– Quantum communication and more.

Still within the framework of PEPR Quantum Technologies, a call for projects, run by the National Research Agency (ANR), was open until March 29 for “on-the-fly” quantum computer projects and a series of calls for projects targeting support themes that complement those explored by the targeted projects already selected will be launched in the spring. These calls will be open to teams or researchers who wish to join the field of quantum technology by contributing the knowledge they have developed in other fields.

The 10 targeted projects by PEPR Quantum Technologies

In the realm of robust solid-state qubits for quantum computing

Two projects were selected for their potential for the development of large-scale quantum computers.

To have access to a world-class technological platform, the project PRÆSQUILE aims to help identify and remove the scientific and technological barriers to the integration of spin-qubits into well-established CMOS technologies.

The project Robust SuperQ aims to accelerate French research and development on superconducting and hybrid qubits protected by construction against decoherence, a phenomenon that makes qubits unreadable and creates random errors: in 5 years, the project will demonstrate a controllable and measurable high-fidelity quantum processor that has not yet exists on any platform (optical, atomic or solid state).

In cold atom qubits for quantum computation and sensors

The project QubitAF aims to improve cold atom platforms for quantum simulation by increasing the number of atoms handled, by certifying the results and by specifying the performance of these platforms.

The project QAFCA seeks to develop compact and portable cold nuclear sensors for measuring the gravitational field with applications in climate change analysis and anticipation of natural disasters, even civil engineering or CO2 storage.

In error-correcting codes, quantum algorithms, and post-quantum cryptography

The project NISQ2LSQ aims to improve and develop new error correction strategies needed to implement error-tolerant quantum computers. Three approaches are maintained: bosonic codes, photonic codes, and LDPCs.

The project EPiQ focuses on the specification and understanding of the software blocks required for the proper functioning of a quantum processor (compilation, manipulations, optimization, intermediate languages, certification, etc.). It also aims to develop new quantum algorithms in areas such as machine learning, optimization or chemistry, as well as to facilitate the simulation of existing machines to better understand their operation.

The project PQ-TLS develops new encryption and signature schemes, based on a wealth of approaches, to bring cryptography to the post-quantum era, that is, to make protocols resistant to cyber attacks. to a quantum computer.

In quantum communication

The project DIQKD is interested in the quantum distribution of “black box” type keys, a promising but demanding solution in terms of experimental and theoretical development, which makes it possible to guarantee communication security, even when the devices used are only partially characterized.

The project Qmemo aims to optimize the performance of quantum memories, crucial elements for implementing long-distance quantum networks as they connect the sub-segments that share the global distance as quantum repeaters.

The project QcommTestbed wants to provide France with a nationally coordinated testing platform used for demonstrations of quantum communications applications via a gradual increase in TRLs, ranging from laboratory systems to commercial products.

PEPR also funds two EquipEx + structuring equipment: aQCess, piloted by the University of Strasbourg, which offers a quantum computer platform based on cold atoms as a service, and e-DIAMANT, piloted by the École Normale Supérieure Paris-Saclay and strongly coupled with industry whose ambition is to become a leading diamond supplier for quantum applications by developing the entire chain, from the material to the device.
